Heddle frame

Patented Dec, 2, 1930 DLE MANUFACT TIQN or PENNSYLVANIA Applicationfiled November My invention relates to heddle'frames for that type ofheddle, frame in which individual warp controlling heddles are. mountedon supporting bars carried by-"the frame. 7 1

tion is to provide a h'eddle frame of greatly improved construction, inwhichthe end members, as welllas the top and bottom rails are: madeiofrelatively thin strips fofwood or similar material, reinforced bymetallic" strips, and in which the end members will be moreeflicientlyifs'ecured to the top and bottom rails.

. A further object vide improved means for securing the heddlesupporting bars in place, which willfb'e inexpensive yet efficient,which will not be'like- 1y to become detached in use, and which may bereadily rem v d,- or. enl stme "when The nature and characteristicfeatures of my invention will be more readily understood from thefollowing description, taken in connection with the accompanyingdrawings forming part hereof, in which:

Figure 1 is a side elevation of a heddle frame embodying the mainfeatures of my present invention;

Referring tothe drawings, the heddle frame proper may comprise top and bottom rails6 and end members 7, all of which are preferably made of relatively thinstrips of The end members 7 may be reinforced by metallic strips 8 ontheinner faces of the of myinventioii istopro- 'Jorm ,mcoejmvgmm', or stemJena-K, PEnNsrtvAN IA, AssIe oRTo s'rEELnEn URING COMPANY, .01,PHILADELPHIA, PENNSYLVANIA, econrona HEDDLE FRA E 1 is, i328." s t li319,777.

The end portions of the reinforcing strips 8"are bent over at'rightangles and extend along the innerfaces of the top and bottom Theprincipal. object of mypresent inven;

' The outer reinforcing strips-9 .extend overf the endportions of thetop and bottom rails 6, andare bent over, as at 12,- andsecured to theouter T faces of the top and bottom rails 6 byscrews 13. i 7 Rivets 14,extending at various places throughthe wooden" end members 7 secure thereinforcing strips'.8 and 9 thereto and to" each other.

The heddle ,sii poitiiig' bars 15, with the needles 16"arranged-'thereon in the usual manner, are mounted in the frameby having their endportions extending through slots 17 providedin the end members 7, andthrough complementary, slots 18, and 19 provided inthe'reinforcingstrips 8 and 9, respectively.

The ends of the heddle supporting bars project beyond the outerreinforcingstrips 9, and these end portions of the heddle supportingbars are apertured as at 20, for engagementby' the securing devices.

Each of the securing devices 'comprises a member 21, shown'ln detacheddetail in'Fig. 5

of thegdrawings, and preferably made of a spring steel wire. One end ofthe member 21 has a bent over hook-like extension22, which is adapted toengage the aperture 20 in the end ofthe heddle supporting bar 15.

, The" other end. offthe securing device 21 which is'adapted to bepositioned in a transverse. hole in-the end member 7, being held thereinby'frictional engagement.

Adjacent the bent over'eKtension' 23, the body portion "of the securingdevice 21' isprovided with an inset portion 24, which is adapted to beseated in aslot 25 provided in the outer reinforcing strip 9;

is alsoprovided with a bent over-extension 23, 1

Between the ins'etportion 24 and-th e be nt over extension 23 islasemi-circular loop '26," which eXtends beyond-the outer surface; of

be {presently explained.

the reinforcing member*9, fora purpose to 'I u I In mounting the heddlesin the frame, after the same are properly arranged upon the heddlesupporting bars, the heddle supporting bars are then inserted in theslots 17 in the end member 7, also passing through the complementaryslots 18 and 19 of the reinforcing strips 8 and 9.

The extension 22 of the securing members are then sprung into engagementwith the apertures 20 provided in the ends of the heddle supporting bars15, thereby maintaining the same against displacement. 7

It may here be noted that the engagement of the inset portion 24 of thesecuring device 21 with the slot 25 in thereinforcing strip 9, willserve to prevent the securing device 21 from rotating about theextension 23 as an axis, thereby preventing accidental disengagement ofthe hook-like extension 22 from the aperture 20 in the lieddlesupporting bar.

It will also be noted that by reason of the extension of thesemi-circular loop 26 of the securing device beyond the outer face ofthe reinforcing strip 9, there is provided a ready means for removal ofthe extension23 of the securing device from the strip 7 in the event ofbreakage of the securing device.

It will be'seen that there is thus provided aheddle frame of improvedconstruction, in which likelihood of disengagement of the securing meansfrom the heddle support-ing bars is reduced to a minimum, and in whichthe replacement of 'a broken securing device is greatly facilitated, anddamage to the frame in the removal of the broken part therefrom iseliminated. j

Having thus described the nature and characteristic features of myinvention, what I claim as new and desire to secure by Letters Patent,is:

1. A heddle frame comprising topjand bottom rails and end members;metallic reinforcing strips on the inner and outer faces of said endmembers, the ends of said reinforcing strips being bent over and securedto the top and bottom rails; heddle supporting bars mounted in saidframe extending through slots inthe end members andin thereinforcingstrips, said heddle supporting bars having their ends projecting beyondthe outer reinforcing strips; securing devices each ad apted to engageone of said projecting end portions of a heddle supporting bar andcomprising a member made of spring wire having one end thereof engagingthe end of the heddle supporting bar, and having the other end thereofbent over and extending into the end member; the securing member havingan inset ,portion adjacent the portion which extends into the endmemberofthe frame,'tl1e outer reinforcing strip having a slot in whic i saidinset portion is seated, and the securing memberhaving a loop adjacentthe portion which extends into the end member, said loop extendingoutwardly beyond the transverse plane of the adjacent portion of thesecuring member and beyond the outer face of the outer reinforcingstrip.

2. A heddle frame comprising top and bottom rails and end members;metallic reinforcing strips on the inner and outer faces of said. endineinberspthe ends of saitl reinforcing strips being bent over andsecured to the top and bottom rails; heddle supporting bars mounted insaid frame extending through slots in the end members and in thereinforcing strips, said heddle supp-biting bars having their endsprojecting beyond the outer reinforcing strips and having apertures provided in said projecting portions; securing devices each adapted toengage one of said projecting end portions of a heddle supporting barcomprisinga men'iber niade of spring wire having one end thereof bentover and engaging the aperture inthe end of the' heddle supportingbar,and having the other end thereof bent over and'extending into the endmanner; the securing member having an iii p'o" tion adjacent the portionwhich exls into'fhe end in'ember'of the frame, the reinforcing striphaving a slot in which diiiset portion is Seated, an'dthe securingmember havng a loop adjacent the portion which extends into the endmember, said loop extending outwardly beyond the outer face of thetransverse plane of the adjacent "portion of the securing'nie'inbei"andbeyond the outer reinforcing strip. j t
